1
Q

Anatomy

A

Made up of :
 Ilium
Ischium
Pubis

Fusion begins around age 16

Involved in 3 major joints
SI
Pubic Symphysis
Acetabulum

2
Q

Self-Bracing Mechanism

A

Attained by form + force closure

Model that allows for efficient locomotion and weight transfer

Form closure via structural anatomy of wedge shaped sacrum

Force closure requires horizontal, compressive force and friction to withstand vertical load

3
Q

Dorm Closure

A

Structural anatomy of the wedge shaped sacrum

Internal structure of the sacroiliac joints

4
Q

Force Closure

A

Creates compressive lateral force and friction to withstand vertical load

Accomplished by:
Sacrotuberous and sacrospinous ligaments
Multifidus, Latissimus dorsi, Piriformis, Gluteus maximus, biceps femoris

5
Q

3 types of movements

A

Rotation
 Anterior
 Posterior

Flaring
 Lateral
 Medial

Shearing
 Superior
 Inferior

Rotation and flaring are physiologic and shearing is non-physiologic

6
Q

Innominate Diagnosis

A

Standing flexion test

Landmarks
Anterior superior illiac spine
Posterior superior iliac spine
(pubic rami)

7
Q

Standing flexion test

A

Give the lateralityof the somatic dysfunction

Positive test on the right = right innominate somatic dysfunction

8
Q

Anterior rotation happens with

A

extension of the hip

9
Q

Posterior rotation happens with

A

flexion of the hip

10
Q

Anteriorly Rotated Innominate

Diagnostic Criteria

A

(+) Standing Flex test-ipsilateral
ASIS inferior (caudad)
PSIS superior (cephalad)
Inferior pubes -ipsilateral

11
Q

Anteriorly Rotated Innominate

Etiology

A

Tight quads, leg length discrepancy

12
Q

Anteriorly Rotated Innominate

Patient may c/0

A

hamstring tightness, spasm or even sciatica on ipsilateral side.

13
Q

Posteriorly rotated Innominate

Diagnostic Criteria

A

(+) Standing Flex test-ipsilateral
ASIS superior (cephalad)
PSIS inferior (caudad)
Superior pubes-ipsilateral

14
Q

Posteriorly rotated Innominate

patient may c/o

A

inguinal/groin pain (due to rectus femoris dysfunction)

Medial knee pain (due to sartorius dysfunction)

15
Q

Innominate Flare

A

Lateral positional change
ASIS medial or lateral compared to its usual position
May be thought of as rotation of an innominate along a vertical axis

16
Q

Medial Flare

A

Diagnostic Criteria on Side of Restriction:
(+) Standing Flex test-ipsilateral
ASIS medial
PSIS lateral

Patient may c/o pelvic or sacroiliac joint pain.

Tender sacroiliac ligaments and inguinal ligaments (on either side), tender pubic symphysis
Treatment: ME

17
Q

Lateral Flare

A

Diagnostic Criteria on Side of Restriction:
 ASIS lateral
PSIS medial
(+) Standing Flex test-ipsilateral

Patient may c/o pelvic or sacroiliac pain.

Tender sacroiliac ligaments and inguinal ligaments (on either side)
Treatment: ME

18
Q

Innonimate Shear

A

Traumatic positional change

Apparent vertical transmission of the entire innominate within the S-I joint, either superiorly or inferiorly

19
Q

Superior innonimate Shear

A
Diagnostic Criteria on Side of Restriction:
    (+) Standing Flex test-ipsilateral
   ASIS superior
   PSIS superior
   Pubic tubercle superior

Patient may c/o pelvic pain

Palpatory findings: Tissue texture changes and tenderness at ipsilateral SI and pubes

20
Q

Inferior innonimate Shear

A
Diagnostic Criteria on Side of Restriction:
   (+) Standing Flex test-ipsilateral
   ASIS inferior
   PSIS inferior
   Pubic tubercle inferior

Patient may c/o pelvic pain.

Palpatory findings: Tissue texture changes and tenderness at ipsilateral SIJ and pubes.

21
Q

Pubic SD

A

Three diagnoses
 Superior
Inferior
Compressed

Generally seen with saddle injuries or other trauma

22
Q

Superior Pubic Shear

A

Diagnostic Criteria on Side of Restriction:
(+) Standing Flex test-ipsilateral
ASIS and PSIS level
Ipsilateral pubic tubercle superior

Patient may c/o pelvic pain or pubic arch pain

Palpatory findings: Tissue texture changes and tenderness at ipsilateral pubes

23
Q

Diagnostic Criteria on Side of Restriction:
(+) Standing Flex test-ipsilateral
ASIS and PSIS level
Ipsilateral pubic tubercle inferior
